Visual Outcomes in Pediatric Patients with Peters Anomaly

PURPOSE: This study aimed to evaluate the visual outcomes of pediatric patients diagnosed with Peters anomaly (PA) in a tertiary eye care center. METHODS: This was a retrospective study undertaken at a single academic center. Clinical records of pediatric patients diagnosed with PA from 2000 to 2017 were reviewed. Parameters recorded included visual acuity (VA), intraocular pressure (IOP), presence of glaucoma, and surgical procedures performed. The impact of PA type on final visual acuity levels was analyzed using generalized estimation equation models. RESULTS: Twenty-one eyes from 11 patients were analyzed. At the final visit, 9 eyes (42.8%) had a VA ≥20/200, while 12 (57%) had <20/200, ranging from 20/250 to no light perception. Of the study cohort, 15 (71.5%) eyes had type I, while six (28.5%) had type II PA. Glaucoma was present in 20 eyes (95%) at the final visit. One eye had dense central leucoma and microphthalmos where IOP could not be measured accurately. Seventeen eyes (81%) underwent at least one intraocular surgery, while the average number of surgeries per eye was 2.9 ± 2.5 (range=0– 9). The type of PA beta(se)=0.53 (0.41), p = 0.20] was not found to be a significant risk factor for worse VA. CONCLUSION: Severe visual impairment develops in the majority of patients with PA. The type of anomaly does not appear to be associated with a worse visual function in patients with PA. Glaucoma develops in a high percentage of this patient population, and thus close monitoring of IOP in this patient population is crucial.
