“…Due to our inclusion criteria, all of our CFPM cases had glaucoma. Of the cases of this condition previously published (Table 4), seven patients had glaucoma (4,(12)(13)(14)(15). Given this and the secondary corneal edema associated with glaucoma, UBM is a useful adjunct in the identification and classification of anterior chamber involvement.…”

Purpose: The purpose of this study was to describe and summarize the clinical features of congenital fibrovascular pupillary membrane-induced secondary glaucoma (CFPMSG).Design: Cross-sectional case series.Methods: Eyes of 32 patients with CFPMSG were enrolled. Demographic data, including gender, laterality, age at presentation, and age at onset of glaucoma were collected. Patients underwent comprehensive ophthalmic examinations and ultrasound biomicroscopy (UBM). CFPMSG eyes were classified into three groups based on UBM findings and intergroup analysis was performed using ANOVA.Results: The average age at presentation was 2.4 ± 4.6 months (mean ± SD) and at glaucoma onset was 3.8 ± 4.5 months. Compared to normal fellow eyes, all affected eyes had increased intraocular pressure (IOP), axial length, corneal diameter, and central corneal thickness, and decreased anterior chamber depth (ACD) (all P ≤ 0.001). Twenty-two affected eyes (68.8%) had evidence of glaucomatous optic neuropathy. Based on iris configuration on UBM, eyes were classified as 53% type I (“U” shape), 34% type II (“Y” shape), and 13% type III (no anterior chamber). IOP in types II (33.8 ± 5.9 mmHg) and III (35.2 ± 5.9 mmHg) was significantly higher than in type I eyes (26.5 ± 5.1 mmHg). The ACD was shallower in type II compared to type I (P = 0.045).Conclusion: Congenital fibrovascular pupillary membrane-induced secondary glaucoma is characterized by ocular hypertension, corneal enlargement and edema, axial length elongation, and glaucomatous optic neuropathy. Glaucoma in this condition is secondary to pupillary block and angle-closure. UBM provides important information for the diagnosis and classification of CFPMSG. This novel classification system demonstrated varying levels of severity and may guide on management of this disease.

Purpose: Several methods have been reported to treat pupil deformities. However, there are some disadvantages to these methods. Here, we introduce the new technique of pupilloplasty. Methods: We retrospectively collected five patients who underwent pupilloplasty by radiofrequency diathermy (RFD) in eyes with acorea or a severe pupillary fibrous membrane. The RFD tip was inserted into the anterior chamber after injection of an ophthalmic viscosurgical device (OVD). It was then used to resect the iris and fibrous membrane around the pupillary centre to restore a centred and round pupil. Results: No obvious bleeding was observed during resection of the iris or fibrous membrane with the RFD technique. All cases were successfully treated, and pupil transparency was restored. Conclusion: We introduced a new technique of pupilloplasty by RFD that is easily manageable, reduces bleeding, and is suitable for most types of pupillary seclusion, especially for acorea and severe pupillary fibrous membrane.

“…6 7 Several surgical approaches for removal of the membrane in CFPM have been reported; however, there is limited data on surgical treatment and prognosis for glaucoma secondary to CFPM. [8][9][10] Unlike CFPM, surgery for CFPMSG was more complicated due to the high IOP, corneal opacity, shallow anterior chamber depth (ACD) and tight adhesion of membrane and lens capsule. It is more challenging for intraoperative manipulation and postoperative stability.…”

AimsTo evaluate the efficacy and safety of anterior segment reconstruction (ASR) in congenital fibrovascular pupillary membrane-induced secondary glaucoma (CFPMSG) basing ultrasound biomicroscopy (UBM) classification.MethodsThis ambispective cohort study enrolled patients with CFPMSG who underwent ASR between January 2014 and September 2020. Comprehensive ophthalmic examinations and UBM were performed before surgery and postoperatively. The patients were classified into three types according to the UBM configurations. Anterior chamber recovery (ACR) was defined as deepening in anterior chamber (≥1.5 mm all through final follow-up (FFU), while success following ASR was defined as ACR and intraocular pressure (IOP)≤21 mm Hg.Results25 eyes of 25 patients underwent ASR (average age at operation 5.8±5.0 months, 48% girls) with FFU 15.8±16.9 months. Enrolled subjects were classified into type Ⅰ (11 eyes), type Ⅱ (11 eyes) and type Ⅲ (3 eyes). After ASR, 23 eyes (92%) achieved ACR, and the mean ACD increased in all groups (p=0.006, <0.001 and 0.003, respectively). Eyes with types Ⅰ and Ⅱ demonstrated a reduction of IOP (p=0.009 and 0.002, respectively). ASR success rate was highest in type Ⅰ (72.9%) compared with types Ⅱ and Ⅲ (18.2% and 0%, respectively; p=0.011). ASR led to decreased number of antiglaucoma medications for type Ⅰ CFPMSG at FFU (p=0.016). No vision-threatening postoperative complications occurred.ConclusionsASR for CFPMSG results in increased ACD and improvement in IOP. Postoperative IOP control was best in type Ⅰ CFPMSG but not as effective in types Ⅱ and Ⅲ. UBM-based classification helps to predict the surgical outcome of ASR in CFPMSG.
