ABSTRACT
Purpose: To assess the change in binocular summation (BiS) in comitant exotropia (XT) after strabismus surgery. Methods: This is a prospective study on 20 patients who underwent surgery for comitant XT over a one year period. Patients with sensory exotropia and nystagmus were excluded. Best?corrected visual acuity (VA) and contrast sensitivity (CS) of both eyes separately and together (binocularly) were recorded. BiS score was calculated as binocular score minus better eye score. BiS score at the end of 3 months was compared with the preoperative data. Results: The mean ± SD of BiS score increased from 2.95 ± 0.88 to 4.55 ± 0.68 (P?value < 0.0001) for VA (on ETDRS letters) and from 2.75 ± 0.44 to 4.5 ± 0.76 (P?value < 0.001 for CS (on Pelli–Robson chart) after surgery. Conclusion: There is significant improvement in BiS in XT after strabismus surgery. Authors recommend its inclusion in evaluation of functional outcome of XT surgery
ABSTRACT
Purpose: To evaluate the outcome of transscleral fixation of closed loop haptic acrylic posterior chamber intraocular lens (PCIOL) in aphakia in nonvitrectomized eyes. Materials and Methods: Patients with postcataract surgery aphakia, trauma with posterior capsule injury, subluxated crystalline lens, and per operative complications where sulcus implantation was not possible were included over a 1‑year period. Scleral fixation of acrylic hydrophilic PCIOL was performed according to the described technique, and the patients were evaluated on the day 1, 3, 14, and at 3 and 12 months postoperatively for IOL centration, pseudophakodonesis, change in best‑corrected visual acuity (BCVA), and any other complications. Results: Out of twenty‑nine eyes of 24 patients, who completed the study, 25 (86.2%) eyes had improved, 2 (6.9%) eyes showed no change, and 2 (6.9%) eyes had worsening of BCVA. Three (10.3%) eyes developed postoperative complications. A significant improvement in mean BCVA (P < 0.0001) was observed after the procedure. Mean duration of follow‑up was 26.2 months (range 22–35 months). Conclusion: The use of closed loop haptic acrylic IOL for scleral fixation appears to be safe and effective alternative to conventional scleral fixated polymethyl methacrylate intraocular lenses.
ABSTRACT
Aim: The aim of this study was to evaluate the clinical, socio‑economic, and demographic factors associated with the severity at presentation among juvenile primary open angle glaucoma (JOAG) patients. Materials and Methods: Age at diagnosis, family history, baseline intraocular pressure (IOP), access to health‑care, socio‑economic status, and glaucoma awareness among 80 unrelated JOAG patients presenting between 10 years and 40 years of age were analyzed for their association with the severity at presentation. Severity at presentation was graded based on worse eye visual field using the advanced glaucoma intervention study score and on binocular visual field defects at presentation. Results: Patients with a positive family history presented 4 years earlier (P = 0.045, confidence interval [CI]: 0.09‑8.8) compared to those without a family history. Lower socio‑economic status (Odds ratio [OR] 5.7, P = 0.01, CI: 1.5‑22), and higher baseline IOP (OR 7, P = 0.003, CI: 1.9‑26) were associated with severe glaucomatous visual field defect at presentation. A negative family history was associated with a 10 times likelihood of presenting with a severe glaucomatous field defect (OR 0.1, P = 0.007, CI: 0‑0.5). Conclusions: Clinical, socio‑economic, and demographic factors are contributory to the severity at presentation among young patients with early onset glaucoma. Presence of a family history is associated with an earlier presentation among these patients and a reduced risk of the severe presentation
