A 13-year-old female patient with refractory primary congenital glaucoma (PCG) in the right eye who had a history of multiple glaucoma operations underwent ab interno 180-degree trabeculectomy with the Kahook Dual Blade (KDB) targeting the nasal and inferior angles. On postoperative day 1, the intraocular pressure (IOP) of the right eye reduced from 43 to 15 mmHg while on medical therapy. The patient maintained this IOP level throughout the 6-month follow-up. Ab interno KDB trabeculectomy targeting both nasal and inferior angles may be an effective and safe procedure for the treatment of PCG even in eyes with a history of previously failed glaucoma procedures.

Introduction: Primary congenital glaucoma is a rare ocular disorder that is responsible for 0.01%–0.04% of total blindness worldwide.1 The goal of congenital glaucoma management is to allow for proper development of the immature visual system by controlling intraocular pressure. Medical therapy usually provides a supportive role to temporarily reduce intraocular pressure, but patients typically require iridocorneal angle surgery to facilitate aqueous humor outflow. In this report, we describe the use of minimally invasive ab interno Kahook Dual Blade trabeculectomy for treatment of primary congenital glaucoma. Case description: A 13-month-old male with bilateral primary congenital glaucoma due to a loss of function TEK mutation. He had bilateral findings of elevated intraocular pressures, buphthalmos, Haab’s striae, photophobia, and myopia. Over the course of 6 weeks, three ab interno trabeculectomies with a Kahook Dual Blade were performed in the patient’s left eye and one in the patient’s right eye. After 3 months, intraocular pressures while receiving pressure reducing ophthalmic drops bilaterally reduced from 43 to 21 mmHg in the right eye after a single surgery and from 44 to 34 mmHg in the left eye after three surgeries, eventually requiring glaucoma drainage implant placement. There were no complications. Conclusion: Ab interno Kahook Dual Blade Trabeculectomy is a minimally invasive and potentially successful procedure for the treatment of congenital glaucoma. The safety profile of minimally invasive glaucoma surgery warrants consideration for congenital glaucoma patients, as they usually require iridocorneal angle surgery because pharmacologic therapy is typically inadequate.

Objective: To assess incidence and risk factors of cataract extraction in patients with primary congenital glaucoma, surgical outcome, and complications. Material and method: Retrospective cohort study, in which 108 patients with primary congenital glaucoma were included. Data collected were need for cataract extraction and at what age, intraocular pressure at diagnosis of primary congenital glaucoma, required antiglaucomatous surgeries, possible mutation in the CYP1B1 gene, and final visual acuity. Among the patients who required cataract extraction were visual acuity, intraocular pressure, and complications, evaluated preoperatively and postoperatively. The data were analysed with STATA. Results: A total of 198 eyes of 108 patients were included, with a median follow-up of 8 years (range: 5–53). In all, 32 eyes (16.2%) of 24 patients (22%) required cataract extraction. The median age for cataract extraction was 12.94 years (interquartile range: 2.42–22). The main identified risk factors associated with cataract extraction were antiglaucomatous surgeries (hazard ratio 1.48, p < 0.001) and valvular implant (hazard ratio 2.78, p < 0.001). Lens was implanted in 30/32 eyes and the main complications were intraocular pressure decontrol ( n = 13), capsular fibrosis ( n = 7), corneal decompensation ( n = 4), lens subluxation ( n = 4), and endophthalmitis ( n = 1). Visual acuity improvement was observed after cataract extraction in 66.67% of eyes. Conclusions: There is a high incidence of cataract surgery in patients with primary congenital glaucoma, but generally outside of pediatric age. A greater risk of cataract extraction was identified in those patients with a greater number of antiglaucomatous surgeries, especially after valvular implantation. Despite the high rate of complications related to cataract extraction in primary congenital glaucoma, good visual improvement was observed after surgery.

A 65-year-old female patient has a history of malignant triton tumour of the right upper lobe of the lung. She underwent right upper lobectomy and lymphadenectomy in May 2018. She presented in November 2019 with pathological fracture of the left proximal femur. It was not associated with neurofibromatosis. We decided to do an excisional biopsy of the mass and proximal femoral replacement followed by radiotherapy. Four months later, she presented with local recurrence. We organised a multidisciplinary team between the orthopaedic, histopathology and oncology teams. Then, we decided to treat her with chemotherapy. After 2 months of follow-up, she responded well to the chemotherapy with no further deterioration of her condition.

Background/Objectives To describe intraocular pressure (IOP) and ocular hypotensive medication outcomes of combined phacoemulsification and ab interno trabeculectomy with the Kahook Dual Blade (KDB; New World Medical, Inc, Rancho Cucamonga, CA) in adults with cataract and open-angle glaucoma (OAG). Subjects/Methods Retrospective chart review of existing medical records. Data collected included intraocular pressure (IOP) and IOP-lowering medication use preoperatively and through up to 24 months postoperatively. Paired t-tests were utilized to compare preoperative to postoperative mean IOP and mean medications used. Results Data from 32 eyes of 26 subjects were analyzed. Subjects were predominantly Caucasian (25/26) had mean (standard error) age of 79.3 (1.2) years, and eyes had moderate-advanced OAG (mean visual field mean deviation -8.3 [1.3] dB). Mean IOP was 19.8 (0.8) mmHg at baseline and 15.5 (0.6) mmHg (p<0.0001) after mean follow-up of 11.5 (1.0) months; IOP reductions of ≥20% were achieved in 20/32 eyes (62.5%). Mean medication use declined from 2.4 (0.2) medications per eye at baseline to 0.5 (0.2) at last follow-up (p<0.0001); 23/32 eyes (71.9%) were medication-free at last follow-up. No vision-threatening complications were observed. Conclusions Combined phacoemulsification and ab interno trabeculectomy with the KDB safely provided mean IOP reductions of 21.7% and mean IOP medication reductions of 83% after mean follow-up of 12 months in eyes with moderate to advanced OAG. This procedure provides medication-independence in most eyes with statistically and clinically significant IOP reductions.

Faciomaxillary and ocular trauma is a common entity in most emergency and trauma units. We came across a 68-year-old female patient with a history of bull horn injury over the right eye. Examination revealed an empty orbital socket with unreliable perception of light present. Imaging showed that the eye had displaced posteroinferomedially to be lying in the ethmoid air cells in the nasal cavity. Under nasal endoscopic guidance, the eye was reposited back into the orbital socket and conjunctival sutures were taken to stabilize the position. The patient had vision of counting fingers at 1.5 m on the first postoperative day which improved to 6/24 on last follow-up. Such is the rarity that never before has such a case been described in literature where traumatic displacement of eyeball into the nose has been successfully repositioned by an endonasal endoscope with appreciable regaining of vision. It also further promotes endonasal endoscopic approach in the management of orbital blow out injuries.

Purpose To assess the long-term results of viscotrabeculotomy in infants with primary congenital glaucoma and to compare its outcome with conventional trabeculotomy. Patients and methods A prospective randomized comparative study included infants with primary congenital glaucoma younger than 2 years. Patients were divided into two groups: viscotrabeculotomy group and conventional trabeculotomy group. Preoperative and postoperative intraocular pressures, corneal diameter, intraoperative and postoperative complications, and success rates were compared between two groups. All the patients were followed up for 5 years. Results The study included 154 eyes of 92 infants distributed randomly among the two groups; 78 and 76 eyes in viscotrabeculotomy and conventional trabeculotomy groups, respectively. In both groups, there was a statistically significant intraocular pressure reduction at all time points of the follow-up periods compared to the preoperative values (p < 0.0001). At 5 years, viscotrabeculotomy group showed significant reduction of the mean postoperative intraocular pressure (49.47%) than conventional trabeculotomy group (48.64%) (p < 0.0001). Intraocular pressure was statistically lower in viscotrabeculotomy starting from 12th month and till the end of the follow-up. At 5 years, the total success rate of viscotrabeculotomy group was 89.74% compared to 85.53% in conventional trabeculotomy group without significant difference (p = 0.487). The postoperative mean values of the cup/disk ratio in viscotrabeculotomy group showed statistically lower values compared to conventional trabeculotomy group (p = 0.019). Postoperative hyphema was statistically higher in conventional trabeculotomy group (p < 0.0001). All eyes that underwent a reoperation before 5 years follow-up were excluded from the statistical workup of the study after reoperation, except for calculation of success/failure. Conclusion Viscotrabeculotomy and conventional trabeculotomy proved to be effective in cases of primary congenital glaucoma. Viscotrabeculotomy appeared to have prolonged stability in controlling the intraocular pressure with higher success rates and lower complications.

Visual Outcomes

Purpose: To evaluate the long-term visual outcomes of ab externo trabeculotomy for primary congenital glaucoma (PCG) at a single pediatric ophthalmology center. Methods: In this retrospective single-center case series, data from 63 eyes of 40 patients who underwent ab externo trabeculotomy between September 2006 and June 2018 were included. The data were analyzed for best corrected visual acuity (BCVA), stereopsis, and surgical success. Kaplan–Meier analysis was performed using the surgical success criteria defined as intraocular pressure (IOP) ≤ 21 mmHg and ≥ 20% below baseline without the need for additional glaucoma surgery. Results: BCVA at the time of diagnosis was 0.37 ± 0.48 logMAR, which changed to 0.51 ± 0.56 logMAR at the final follow-up (P = 0.08). Twenty-five percent of patients had BCVA equal to or better than 20/40 at the final visit. The mean refraction at baseline was –4.78 ± 5.87 diopters, which changed to less myopic refraction of –2.90 ± 3.83 diopters at the final visit. Optical correction was prescribed in 66% of eyes at the final visit. The average final stereopsis was 395.33 sec of arc. The linear regression model showed a significant association between the surgery success rate and final BCVA as well as stereoacuity (Pvalues: 0.04 and 0.03, respectively). Intraocular pressure (IOP) decreased significantly from 29.79 ± 7.67 mmHg at baseline to 16.13 ± 3.41 mmHg at the final follow-up (P = 0.001). Conclusion: Patients with PCG can achieve an acceptable visual acuity and stereoacuity, particularly in cases of timely intervention and close follow-up.

Objective: To determine the surgical outcomes of combined trabeculotomy- trabeculectomy with mitomycin-C and releasable suture in children with primary congenital glaucoma (PCG) in a North Indian population. Design: Retrospective, interventional, consecutive, non-comparative case series. Materials and methods: The medical records of 137 eyes of 77 patients who underwent combined trabeculotomy- trabeculectomy with 0.2 mg/ml mitomycin C (MMC) either bilaterally (49 patients) or unilaterally (28 patients) between January 2004 and March 2012 were reviewed retrospectively. The main outcome measures were postoperative intraocular pressures, corneal clarity and diameter, duration of follow-up, success rate and complications. Results: The mean preoperative intraocular pressure reduced from 34 ± 7 mm Hg (range 15- 54 mm Hg) to 17 ± 7 mm Hg (range 5 - 32 mm Hg) with a mean reduction of 44 % (P < 0.001). The mean follow-up period was 24.4 ± 10.3 months (range 6 – 48 months). Complete success defined as intraocular pressure < 21 mm Hg without any medication and clinically stable glaucoma at last follow-up was achieved in 113 eyes (83 %) while a ‘quali¿ed success’ of intraocular pressure < 21 mm Hg with one medication was achieved in ten eyes (7 %). The Kaplan-Meier survival analysis revealed success rates (at ‘n’ months) of 90 % (6), 85 % (12), 82 % (24), 80 % (36) and 77 % (48). There were no signi¿cant intraoperative or postoperative complications.Conclusion: Primary combined trabeculotomy-trabeculectomy with mitomycin-C and releasable suture offers a viable surgical option in Northern Indian infants with primary congenital glaucoma. The use of 0.2 mg/ml mitomycin C for 2 minutes improves the overall success while the releasable suture decreases the risk of postoperative complications especially associated with the use of antimetabolites.
