“…[31] In another UBM study of haptics in trans sclera fixated IOL, it was reported that correctly placed haptics was present in 33% cases; where as 50% were located posterior to the sulcus and 17% were placed anterior to the sulcus. [32] Various methods for ciliary sulcus localization have been used and are reported in literature eg., transillumination with endo-illuminator [31] and mirror needle holder. [33] With transillumination technique of localization of ciliary sulcus, haptic placement in sulcus improved to 64%.…”

The purpose of the study was to evaluate the feasibility of ophthalmic endoscope as a diagnostic tool. This was a prospective, non-comparative, interventional clinical study of 11 consecutive patients who underwent endoscopy-assisted management for ocular pathologies. We used a fused fiber-optic type of endoscope to visualize areas of the eye which were not seen clearly, due to media opacity, through conventional viewing systems like indirect ophthalmoscopy or wide angle viewing system. Eleven cases were enrolled in the study. Five patients underwent endoscopic examination of the fundus prior to penetrating keratoplasty (PKP) or keratoprosthesis. In one out of these 5 cases, PKP was differed due to pale optic nerve. Patient number 6, 7 & 8 were cases of recurrent vitreous hemorrhage. In these patients, endoscope was used to inspect the sclerotomy from inside and to remove incarcerated vitreous and fibro-vascular membrane. Patient number 9 was a case of poorly dilating pupil undergoing cataract surgery. Endoscope was used in this patient to locate the exact position of haptics of PCIOL. In cases 10 and 11, endoscope was used to localize ciliary sulcus and to document the position of haptics of sclera fixated IOL. Conclusion: The ophthalmic endoscope provides valuable information by illuminating, video recording, and by providing clear view of areas not visible by conventional viewing systems. It can help in management strategies in selected cases.

“…Ultrasound biomicroscopy, a technique that allows for a real time panoramic view to image the anterior segment, revealing the ciliary body and peripheral retina, was found as an adjuvant tool to evaluate the placement of the IOL postoperatively [19, 20]. …”

“…In another study by Alp et al, UBM examination showed that the rate of haptics located in the sulcus was statistically significantly higher in the endoilluminator-assisted group (64%) than in the control group (24%) ( p = 0.001), which reflects the limitations of the blind needle penetration method for precise suturing in the ciliary sulcus [19]. …”

Purpose. To evaluate the short-term postoperative outcomes in endoscopic-assisted sclera fixation intraocular lens (IOL) for the management of secondary aphakia in children. Methods. This is a prospective study, whereas 40 aphakic eyes with absence of a good capsular support were implanted by endoscopy-assisted sclera fixation technique. Results. No major intraoperative complications were recorded. All cases were followed up for 6 months. Only transient ocular hypertension occurred in 10 (25%) eyes. Lens decentration and/or tilting were clinically detected in 2 eyes (5%). Ultrasonic biomicroscopic (UBM) examination revealed lens tilting in 2 (5%) of the operated eyes, despite the proper haptics positioning in the ciliary sulcus. Postoperative vitreous hemorrhage was reported in 5 eyes (12.5%) in the early postoperative period and retinal detachment in one eye. A postoperative refractive astigmatism ranging from 0.75 D to 3.75 D (mean 1.7 D ± 0.79) was recorded, as compared to mean preoperative values of 2.00 D, with no statistically significant differences being recorded (p ≥ 0.05). An improvement of BCVA, 1-2 lines on Snellen chart at the end of the follow-up period, was detected in 23 eyes (57.5%) with a mean of 0.6 ± 0.08 SD, as compared to a preoperative mean values of 0.5 ± 0.07 SD (p ≥ 0.05). Conclusion. Using an endoscope for transscleral suturing of intraocular lenses in aphakic pediatric eyes might be considered as being an effective technique that can reduce surgical complications, especially postoperative lens decentration.

In adults, STI reveals two dark bands separating a light band with the anterior dark band corresponding with the pars plicata and light posterior band to the pars plana, whereas in infants a single dark band is apparent.…”

Importance There is variation in the literature for sclerotomy and intravitreal injection placement in young children, ranging from 0.5 to 3.0 mm from the limbus. We assess the accuracy of scleral transillumination to identify the ciliary body in infants for safe sclerotomy and intravitreal injections in young children. Background The study compares the perilimbal “dark band” seen on scleral transillumination (STI) with the ultrasound biomicroscopy (UBM), and compares these measurements with the current guidelines for sclerotomy in infants. Design Prospective case series in a tertiary paediatric hospital. Participants Children aged ≤36 months undergoing general anaesthesia for eye procedures. Methods Scleral transillumination was performed to measure the perilimbal dark band. UBM of the ciliary body region was then performed, and correlated with transillumination findings. Main Outcome Measures The midpoints of STI and UBM were compared to current cadaver‐based guidelines to assess the safe point for sclerotomy. Results Twenty children were recruited, 36 STI and 35 UBM measurements were obtained. The posterior edge of the dark band had good correlation with the posterior border of the ciliary body. Transillumination and UBM correlated well for midpoint measurements. The midpoint of the dark band on transillumination was confirmed to be in the ciliary body by UBM in all cases. Conclusions and Relevance The STI technique is a useful and fast technique to demonstrate the ciliary body. The midpoint of the dark band on STI correlates well with the UBM, and has a potential use for confirming safe‐entry into the posterior segment if using current guidelines. The current cadaver‐based paediatric guidelines safely avoid retinal injury.
