Objective: Creating a model to predict Axial Length (AL) growth in paediatric cataract and evaluating influence factors. Material and methods: Eyes with AL measured at surgery and at least one measurement after a 6-month period, from children with unilateral or bilateral cataract and primary IOL implantation, were evaluated. A “rate of axial length growth” (RALG) was calculated for every single eye using these AL measurements and log10 age. One average RALG was calculated for All Eyes and for the groups of Bilateral and Unilateral, Gender, Age at the Surgery, different Visual Acuity, Bilateral Excluded and Not-excluded eye, and Affected and Not-affected eye in unilateral, for comparisons. Results: Average age at surgery from 76 children was 2.83 ± 2.74 (0.11–12.21) years with follow up of 2.84 ± 1.84 (0.52–8.17) years, 29 (37.66%) had unilateral cataract. A total of 357 AL measurements were used, average of 4.70 ± 2.13 (2–10) measurements per eye. The average RALG for all eyes was 4.51 ± 3.06. There were no RALG significant differences comparing Unilateral and Bilateral eyes ( p = 0.51), Male and Female ( p = 0.26), Age at Surgery <0.5 and >0.5 years old ( p = 0.21), both eyes in Bilateral cases ( p = 0.70) and Unilateral Affected and Not-affected eyes ( p = 0.18). The equation Al = initial AL + slope ×  Log10 ((age +  0.6)⁄(initial age = 0.6)) estimates ALs in different ages. Conclusions: A model to predict AL growth in paediatric cataract was developed. Different studied factors did not significantly influence AL growth.

BackgroundCataract is the leading cause of blindness in developing countries and identification of the barriers to accessing treatment is essential for developing appropriate public healthcare interventions. To evaluate the barriers to cataract surgery after diagnosis and assess the postoperative outcomes in Sao Paolo State, Brazil.MethodsThis prospective study evaluated cataract patients from 13 counties in São Paulo State in 2014. Cataract was diagnosed in the community by a mobile ophthalmic unit and patients were referred to a hospital for management. Gender, age, distance to the hospital and local municipal health structure were evaluated as possible barriers. Data were analyzed for postoperative outcomes and the impact on blindness and visual impairment.ResultsSix hundred patients were diagnosed with cataract with a mean age of 68.8±10.3 years and 374 (62.3%) were females. Two hundred and fifty-four (42.3%) patients presented to the referral hospital. One hundred forty-four (56.7%) underwent surgery, 56 (22.0%) decided not to undergo surgery, 40 (15.7%) required only YAG-Laser and 14 (5.5%) required a spectacle prescription only. Visual acuity increased statistically significantly from 1.07±0.73 logMAR at presentation to 0.25±0.41 logMAR at the final visit after intraocular lens implantation (p=0.000). There was a statistically significantly decrease from 17 (11.8%) blind patients and 55 (38.2%) visually impaired patients at presentation to 2 (1.4%) and 5 (3.5%) patients respectively after treatment (p=0.000).ConclusionLess than half of the individuals with cataract presented to the hospital for surgery. Among the patients who underwent treatment, there was an overall decrease in the number of blind individuals and visually impaired individuals. The barriers to cataract surgery were older age, greater distance to the hospital, municipalities with fewer inhabitants and less ophthalmic services.

We report the case of a 4-year-old boy with Marfan syndrome whose parents reported he had had low visual acuity since birth. On examination, there was microspherophakia and a small subluxation of the lens. The objective refraction was-23.75-2.75 x 70 in the right eye and-25.50-3.50 x 90 in the left eye. Since the microspherophakia and the high myopia severely affected the boy's quality of life, clear lens extraction, anterior vitrectomy, posterior surgical capsulotomy via the pars plana, and intraocular lens implantation were performed. Two years postoperatively, the patient had centered intraocular lenses and a corrected visual acuity of 20/30 in both eyes. The child was satisfied with his vision and was able to study and perform daily activities without visual limitations.
