OBJECTIVE: To analyze torpedo maculopathy (TM) and to report the characteristics of the disease.
METHODS: Retrospective study. The review of a database for clinical diagnosis identified eight patients with TM lesions in the retina between 2016 and 2022. Multimodal imaging was used to analyze the cases.
RESULTS: All cases were unilateral, asymptomatic, and hypopigmented. They were associated by surrounding hyperpigmented retinal pigment epithelium changes to varying degrees. All lesions were located in the temporal retina on the horizontal axis, pointing towards the fovea, except for one patient with a lesion inferior to the fovea. Optical coherence tomography imaging revealed a normal inner retina in all eyes. In the area of the TM lesion, attenuation of the interdigitation zone was seen in mild cases (three cases). All other five patients had thinning of the outer nuclear layer and loss of ellipsoid zone and interdigitation zone of the TM lesion. Four of these cases had a subretinal cavitation/cleft, and two of them additionally an inner choroidal excavation. No patient had any sign of choroidal neovascularization. The average age for patients with type 1 TM was 18 years and for type 2 TM 16.5 years.
CONCLUSIONS: In this large case series, we could not detect an age difference between the different types of the TM. Contrary to previous discussions, type 2 TM can also occur in young patients.

BACKGROUND: Torpedo maculopathy (TM) is a rare, congenital condition characterized by an oval-shaped, chorioretinal lesion in the temporal macula of unknown etiology. To our knowledge, the longest reported follow-up of TM is 5 years. Herein we report 10 years of follow-up on two patients with TM to further characterize the long-term natural history of the condition.
METHODS: Two patients with torpedo maculopathy were examined at baseline and then again at 5 years and 10 years from baseline. Eyes were evaluated using color fundus photography, automated perimetry, fundus autofluorescence and spectral domain optical coherence tomography. Visual function of both patients remained stable throughout the observation period. In case 1, there was no evidence of change in lesion morphology over the 10 year observation period. Case 2 showed progression of cystic degeneration of the neurosensory retina within the torpedo lesion. Case 1 reported a history of supernumerary teeth and underwent gene sequence with deletion/duplication analyses of the APC gene but no clinically significant variants were detected.
CONCLUSIONS: Our findings support the position that TM is a nonprogressive condition with long-term stability of visual function. Genetic analysis of case 1 failed to detect any association with Gardner syndrome.

UNASSIGNED: To report a rare type III torpedo maculopathy lesion with a unique manifestation of subretinal fluid.
UNASSIGNED: A nine-year-old patient was referred to retina for an evaluation of a hypopigmented oval-shaped lesion in the temporal macula with an area of inferior subretinal fluid in the right eye. The lesion demonstrated inner and outer retinal and retinal pigment epithelial attenuation, intraretinal and subretinal fluid, a serous neurosensory retinal detachment, and inner choroidal excavation on optical coherence tomography. Fundus autofluorescence showed a lane of downward-tracking fluid. Intravenously administered fluorescein angiography revealed a window defect in the area of the torpedo lesion suggesting choroidal flush.
UNASSIGNED: The case is the third documented case of torpedo maculopathy with subretinal fluid in the literature with a unique combination of intraretinal cystic changes and dependent descending subretinal fluid, somewhat akin to a Best disease outside of the fovea with choroidal excavation. The morphology of torpedo maculopathy continues to expand as more cases are revealed.

OBJECTIVE: Torpedo maculopathy is an incidental, congenital retinal lesion. The typical clinical finding is a unilateral, symmetric, oval, hypopigmented lesion in the inferotemporal macula. In most cases, the lesion is along the horizontal raphe, is torpedo-shaped, and the nasal edge is directed into the foveola. The diagnosis is determined on the basis of its characteristic shape, localization and findings on optical coherence tomography (OCT). The etiology and pathogenesis of torpedo maculopathy is unclear, but it is believed to be a congenital defect of the retinal pigment epithelium (RPE). The aim of this publication is  highlight this diagnosis and to present an incidental finding of torpedo maculopathy in an adult patient.
METHODS: A 30-year-old female patient reported for a routine eye examination. Fundus examination of the right eye revealed an oval hypopigmented lesion with a size of 1 disk diameter inferotemporally from the fovea, which was followed by a satellite lesion in the same axis directed into the foveola. Based on OCT, OCT angiography, fundus autofluorescence, and the typical shape and location of the lesion, the patient was diagnosed with torpedo maculopathy in the right eye.
CONCLUSIONS: In general, torpedo maculopathy is an asymptomatic, congenital, benign retinal lesion, which is mostly diagnosed accidentally during a routine fundus examination. TM is non-progressive retinal finding with a minimal risk of deterioration of visual functions, which does not require any treatment. Nevertheless, due to the rare risk of a choroidal neovascular membrane, it is recommended to examine patients once a year. It is necessary to consider this diagnosis when a unilateral hypopigmented lesion is found inferotemporally from the fovea, and to distinguish it from chorioretinal atrophy, scar, vitelliform dystrophy, or other RPE lesions as part of the differential diagnosis.

UNASSIGNED: To report a case of proliferative retinopathy with tractional retinal detachment associated with beta thalassemia minor in a 27-year-old female.
UNASSIGNED: A young lady having beta thalassemia minor presented with decreased vision in both eyes, the effect being more severe in her right eye. The patient\'s other systemic history, including ophthalmic history, was unremarkable. The fundus examination revealed peripheral retinal ischemia in both eyes and tractional retinal detachment in the right eye.
UNASSIGNED: Beta thalassemia minor is not associated with striking retinal pathology, nevertheless proliferative retinopathy. However, in this case the patient developed tractional retinal detachment that required surgery. This indicates that proliferative changes may develop in patients with beta thalassemia, and routine fundus examinations could be recommended for these patients.

OBJECTIVE: To report and document a case of torpedo maculopathy found in a patient affected by keratoconus.Case report: An healthy 16-year-old male patient, affected by keratoconus in both eyes, was referred to the cornea service of our hospital for a follow-up visit.During the dilated fundus examination of the left eye, an oval, well-demarcated, hypopigmented lesion was observed in the juxtafoveal temporal region, pointing towards the center of the macula. Multimodal imaging of the lesion was performed, and the diagnosis of Torpedo Maculopathy was established based on the clinical picture.
CONCLUSIONS: This is the first case of torpedo maculopathy described in a patient affected by keratoconus. This association may be merely fortuitous or the result of developmental abnormalities affecting both corneal and retinal structures.

OBJECTIVE: To describe a rare presentation of torpedo maculopathy (TM).
METHODS: A 25-year-old male was examined in the retina clinic for a macular scar in the left eye. His visual acuity was 20/20, N6 in both eyes and no past history of ocular trauma or any medical or ocular history. The anterior segment was quiet and intraocular pressure was normal.
RESULTS: The patient\'s left eye on 78D slit lamp biomicroscopy revealed a flat, diffusely hyperpigmented fusiform torpedo-like lesion with sharp margins and surrounding hypopigmentation located predominantly temporal to the fovea, with its tip pointing towards it and just crossing the vertical foveal midline. Dilated fundus examination with binocular indirect ophthalmoscopy revealed no peripheral chorioretinal lesions or vitritis in both eyes. OCT scan through the lesion revealed gross damage to the outer retinal layers, as well as thickening of the retinal pigment epithelium and underlying shadowing, as well as a hyporeflective subretinal cleft involving the lesion. OCT also revealed outer retinal layer damage with an intact retinal pigment epithelium through the lesion\'s hypopigmented margins. Fundus autofluorescence image revealed a globally hypoautofluorescent lesion in the left eye, with surrounding patchy hyperautofluoroscent areas. Based on the patient history, clinical and imaging findings, other differential diagnoses such as atypical congenital hypertrophy of retinal pigment epithelium (RPE), choroidal nevus, RPE hamartoma, trauma and inflammatory conditions were ruled out. The diagnosis of TM was confirmed based on the typical lesion shape and location.
CONCLUSIONS: A torpedo lesion with diffuse hyperpigmentation is an unusually rare presentation.

Torpedo lesions in the retina are rare, and their clinical significance has not been well established. This case series highlights patients with atypical torpedo lesions with varying orientations and pigmentation patterns. We describe the first documented case of an inferiorly oriented lesion, to our knowledge, and add to the few previous descriptions of double-torpedo lesions.

A 24-year-old woman presented for routine clinical evaluation. Her best-corrected visual acuity was 20/20 and slit-lamp examination of the anterior segment was normal in both eyes. Fundus examination of the left eye revealed a hypopigmented lesion, one disc diameter temporal to the fovea, with a hyperpigmented tail extending temporally from the main lesion, consistent with a torpedo maculopathy. Fundus autofluorescence showed an hypoautofluorescence with hyperautofluorescent border. Swept-source optical coherence tomography (OCT) showed a normal inner retina and a degeneration of the outer retina without retinal cavitation. OCT angiography (OCT-A) of the choriocapillaris layer revealed reverse shadowing caused by the increased transmission from the atrophied outer retina and RPE within the torpedo lesion and attenuation of signal in the area of the temporal hyperpigmentation. The superficial capillary plexus was normal. This case includes a multimodal imaging with OCT-A of torpedo maculopathy in a Tunisian woman. Further reports are required to provide a better understanding of this rare condition.

UNASSIGNED: To report a case of torpedo maculopathy with multimodal fundus imaging methods, and apply the choroid vascularity index to quantitatively describe the choroidal structural changes in torpedo maculopathy.
UNASSIGNED: An asymptomatic 41-year-old Chinese woman with an incidentally found yellowish-white macular lesion in her left eye was referred to our hospital. She was unaware of any prior medical conditions. The best corrected visual acuity (BCVA) was 20/20 OD and 20/25 OS, respectively. Fundus exam of her left eye revealed a well-circumscribed torpedo-like hypopigmented lesion in the macula region, and the tapered edge directed toward the fovea. Pigment deposition could be seen in the inferotemporal portion of the torpedo lesion. Fluorescein angiography showed the corresponding window defect without leakage and fundus autofluorescence demonstrated low signal throughout the lesion. Enhanced depth imaging optical coherence tomography revealed outer retinal attenuation, subretinal cavitation, subtle inner choroidal excavation and thinning of outer nuclear layer. The diagnosis of torpedo maculopathy was clinically made. Choroidal vascularity index (CVI) and sub-foveal choroidal thickness (SFCT) were applied to display changes of choroidal structure. The results implied that both subfoveal CVI and SFCT of the affected eye seemed relatively lower when compared with the fellow eye. Optical coherence tomography angiography showed reduced density of the choriocapillaris in the temporal area of the lesion and increased capillary density in the nasal area. Functional examinations, including microperimetry, multifocal electroretinogram and static perimetry also revealed reduced retinal sensitivity, decreased stimulated amplitude and suspected scotoma in the lesion area. After 12 months of follow-up, the patient\'s visual acuity and the clinical appearance of the lesion were unchanged.
UNASSIGNED: The torpedo maculopathy may be identified by abnormal appearance with multimodal imaging. Decreased choroidal vascularity in the lesion area measured quantitatively by choroid vascularity index may play a role in pathogenesis of torpedo maculopathy.
