OBJECTIVE: This study sought to compare the long-term outcomes of surgeries for retinal detachment (RD) secondary to viral or parasitic infectious retinitis.
METHODS: A total of 47 eyes that received pars plana vitrectomy with or without scleral buckling due to RD secondary to polymerase chain reaction-proven viral (cytomegalovirus, varicella zoster virus, and herpes zoster virus) or parasitic (toxoplasma and toxocara) retinitis from October 1, 2006, to June 30, 2023, in a single medical center were retrospectively enrolled.
RESULTS: Mean follow-up period was 59.03 ± 55.24 months in viral retinitis and 34.80 ± 33.78 months in parasitic retinitis after primary reattachment surgery. During follow-up, nine eyes (24.3%) with viral retinitis and five eyes (50.0%) with parasitic retinitis developed retinal redetachment. Visual acuity success at final follow-up was achieved in 19 eyes (51.4%) with viral retinitis and six eyes (60.0%) with parasitic retinitis (p = 0.64). The incidence of retinal redetachment during the 1st postoperative year was significantly higher in parasitic retinitis compared with viral retinitis (crude incidence, 0.21 vs. 0.85; p = 0.02). Hazard ratio analysis adjusted for age and sex showed 4.58-fold (95% confidence interval, 1.22-17.27; p = 0.03) increased risk of retinal redetachment in parasitic retinitis compared with viral retinitis during the 1st postoperative year. Tamponade with silicone oil and preoperative diagnostic vitrectomy were associated with significantly decreased risk of retinal redetachment in patients with parasitic retinitis.
CONCLUSIONS: Compared with RD secondary to viral retinitis, RD secondary to parasitic retinitis showed higher incidence of retinal redetachment during the 1st postoperative year. Tamponade with silicone oil and preoperative diagnostic vitrectomy were associated with significantly decreased risk of retinal redetachment in patients with parasitic retinitis.

Conjunctivitis is a contagious viral ocular disease that has increased highly in the different areas of Pakistan. Public health data confirmed 86 133 cases in September 2023, which crossed previous any other records. It is confirmed that this infection affects people of all ages, including adults and children frequently. Different clinical symptoms such as painful eyes, redness, inflammation, and augmenting tearing are observed. This infection is responsible for blindness. The transmission of ocular secretion spreads this infectious disease from an infected person to others by contact. In addition current year, less precipitation in Pakistan has impaired the air quality. Temperature, humidity, poor sanitation, polluted air, and other environmental factors are also related to the increase of the disease. This short article aims to present an overview of the rising incidence of conjunctivitis, its probable causes, signs, and symptoms, as well as potential treatments. Using saline for flushing eyes or eye drops is recommended by the Ophthalmologist. A few suggestions such as staying at home, avoiding allergens and contact lenses, washing eyes carefully, and using clean clothes need to be followed for this infection. Multiple immediate action steps are required to prevent and control including heightened public awareness.
