%X UNASSIGNED: The introduction of Highly Active Anti-Retroviral Therapy (HAART) has led to a dramatic decrease in Human Immune Deficiency Virus (HIV) related morbidity and mortality in the developed as well as developing world. Whilst HAART has been effective in reducing rapidly progressive retinopathies, there are other ocular manifestations of HIV which are yet to be determined, characterised and addressed. The aim of the study was to determine the effect of HAART on Accommodative-Convergence mechanism among HIV/AIDS patients in Northwestern, Nigeria.
UNASSIGNED: This was hospital-based cohort study carried out from April 2019 to November 2019. Participants that met the inclusion criteria were recruited and were separated into two groups A and B. Group A were those about to commence HAART referred to as HAART naive, while group B were subdivided into four groups; comprising of B1: those that had been on HAART for 0 - 2½ years, group B2: >2½ - 5 years, group B3: >5 - 7½ years, and group B4: >7½ - 10 years, termed as HAART experience. Information obtained from the patients included sex, age, marital status, Near Point of Convergence (NPC), Amplitude of Accommodation (AA), Presbyopic reading Addition (ADD), CD4+ T cell count, HAART regimen and duration on HAART therapy.
UNASSIGNED: There were 400 participants aged 25 - 55years with a mean age of 37.86 ± 7.5years. The participant's NPC mean was 6.4 ± 1.47cm with a range of 2 - 18cm. Most of the participants 336 (84.0%) had an abnormal Near Point of Convergence compared to 64 (16%) with normal NPC values. The mean AA was 4.18± 1.34DS, ranging from 0.75 to 10.0DS and about 273 (68.2%) of the participant's AA was within 3 to 5DS. The mean presbyopic addition was 1.39± 0.98 DS ranging from 1.00 to 3.50DS whilst majority of the participants, 305 (76.2%) had an abnormal Reading Addition.
UNASSIGNED: The study showed that the HIV/AIDS patients on HAART exhibit an abnormally low AA, receded NPC and High presbyopic reading addition as compared to age matched HAART naïve. There was a statistically significant association between AA and HAART (p = 0.002) and HAART duration (p = 0.00), but there was no association with their CD4+ T cell levels and HAART regimen (p = 0.12, p = 0.08). There was no statistically significant association between Abnormal reading addition and HAART (p= 0.46), CD4+4 T cell levels and HAART regimen (p=0.53 and p= 0.59), but there was a statistically significant association with HAART duration (p= 0.00).
