ABSTRACT
Primary congenital glaucoma usually presents as enlarged and hazy cornea at birth or early childhood. The diagnosis is based on a thorough clinical examination under anesthesia. Most cases require surgical intervention as the definitive treatment. In very rare instances, primary congenital glaucoma may arrest and resolve spontaneously. We describe a case of spontaneously arrested and resolved primary congenital glaucoma in a 37‑year‑old male presenting with large cornea, Haab’s striae, and normal intraocular pressure in one eye. Such a case has not been previously described from the Indian subcontinent.
ABSTRACT
Purpose: To evaluate the outcome of intraocular lens (IOL) implantation using capsular tension ring (CTR) in subluxated crystalline or cataractous lenses in children. Setting: Tertiary care setting Materials and Methods: We prospectively studied 18 eyes of 15 children with subluxation of crystalline or cataractous lenses between 90° up to 210° after phacoemulsification, CTR and IOL implantation. Each child was examined for IOL centration, zonular dehiscence and posterior capsular opacification (PCO). Results: Age of the patient ranged between five to 15 years. Out of 18 eyes, seven had traumatic and 11 had spontaneous subluxation of crystalline or cataractous lens. Phacoemulsification was successfully performed with CTR implantation in the capsular bag. Intraoperative zonular dialysis occurred in two eyes. Anterior vitrectomy was performed in six eyes to manage vitreous prolapse. IOL implanted was polymethyl methacrylate (PMMA) in eight eyes, hydrophobic acrylic in seven and hydrophilic acrylic in three. Follow-up ranged from 24 months to 72 months. Sixteen eyes had a best corrected visual acuity of 20/40 or better. Nine eyes developed significant PCO and were managed with Neodymium Yttrium Aluminum Garnet (Nd:YAG) laser posterior capsulotomy. One eye with acrylic IOL in the capsular bag had IOL dislocation after two years which was managed with vitrectomy and secondary trans-scleral fixation of IOL. Conclusions: Phacoaspiration with CTR implantation makes capsular bag IOL fixation possible in most of the eyes with subluxated crystalline or cataractous lenses. PCO still remains a challenge in children with successful phacoaspiration with CTR implantation

We report a case of an 11-year-old boy who presented two days after blunt trauma to the left eye with a slingshot. On examination his best corrected visual acuity (BCVA) was 20/20 in the right eye and 20/400 in the left eye. Slit-lamp examination of the left eye revealed a Vossius ring, traumatic cataract, traumatic posterior capsule tear (PCT). The contour of the posterior capsule bulge corresponded to the edges of the PCT. Rotating Scheimpflug imaging (Pentacam 70700:Oculus, Wetzlar Germany) confirmed the traumatic cataract in the region of the PCT visualized as increased lens density at the cortex-vitreous interface. The extent of the PCT in the greatest and least dimensions was documented before and after intraocular lens (IOL) implantation. Intra-operatively, the PCT was evident and phaco-emulsification with an IOL implant was performed. Postoperatively, his BCVA improved to 20/20 in the left eye with a well-centered in-the-bag IOL as found on slit-lamp and Scheimpflug images.

PURPOSE: To study the safety profile of primary intraocular lens (IOL) implantation in the first two years of life. MATERIALS AND METHODS: A prospective nonrandomized, interventional study was done at the tertiary care center. Forty-five eyes of 27 children (aged three weeks to two years) with congenital cataract who underwent phacoaspiration with continuous curvilinear capsulorrhexis combined with primary posterior capsulotomy and anterior vitrectomy with in the bag placement of IOL at primary surgery were included. Outcome measures were clarity of visual axis, postoperative inflammation, fixation pattern and retinoscopy. RESULTS: The mean IOL power was 23.95 +/- 0.87 diopter (D) (range 22D to 27D). Follow-up ranged from 12 months to 48 months (mean 18 +/- 9.13 months). In infants, hypermetropia decreased from 6.60D +/- 2.64D at one week postoperatively to 3.03D +/- 2.53D at one year following surgery and 4.78D +/- 1.93D to 2.56D +/- 1.5D in children older than one year at the time of surgery. Re-opacification of the central visual axis was observed in six eyes (13.3%). Significant posterior synechiae due to irido-capsular adhesion was seen in seven eyes (15.6%). Five of these seven eyes also had significant posterior capsular opacification. CONCLUSIONS: Meticulously performed primary IOL implantation and primary posterior capsulorrhexis with anterior vitrectomy in the first two years of life is a safe and effective method of aphakic correction.
