Ultrabiomicroscopy Anterior Segment Evaluation of Ocular Contusive Trauma Caused by Pressurized Bottled Drink Caps: A Case Report

We report the case of a patient presented to the emergency department because of a contusive trauma from a pressurized bottled drink cap. During the visit, the patient indicated that he had been hit in his left eye by a cork while he was opening a sparkling wine bottle. He underwent a total ophthalmology examination. He had an important reduction of visual acuity, corneal swelling, Descemet's folds, and hyphema. Therefore, we decided to perform ultrabiomicroscopy (UBM) of the anterior segment to study the endothelial damage and Descemet's membrane. UBM images confirmed the direct biomicroscopy, highlighting the damaged location.

Developmental changes in accommodation evidenced by an ultrabiomicroscopy procedure in patients of different ages

We demonstrate that changes in the behaviour of the contractile ciliary muscle accompanied by augmented rigidity of the lens are the most important aspects in the loss of accommodation. With ultrabiomicroscopy (UBM), we demonstrated that the performance of the ciliary muscle is diminished and accompanied by rigidity of the lens. Both lens thickness and trabecular-ciliary process distance (TCPD) were the parameters that showed major alterations with the loss of accommodation in patients of different ages. The results indicated that the differences between these parameters in farsightedness and nearsightedness in the different groups of patients were positively correlated.

A study to evaluate whether CTR increases refractive unpredictability between predicted and actual IOL position

BACKGROUND

The surgical management of cataract associated with extensive zonular loss presents a challenge for ophthalmic surgeon. Capsular Tension Ring (CTR) is commonly being used to stabilize the capsular bag in patients with zonular dialysis. CTR helps to avoid capsular collapse and vitreous presentation in AC during surgery and maintains the capsular bag, allowing the circular contour of the capsular bag, allowing intra ocular lens to be easily placed in the bag. The aim of the study was to know if there is any shift of IOL following use of CTR ring.

METHOD

We did a Ultrabiomicroscopy (UBM) examination to find out shift in PCIOL in cases in which CTR ring and compared it with cases without CTR ring.

RESULT

It was found out through UBM in this study that there is actually a posterior shift of PCIOL after use of CTR ring leading to hypermetropic correction needed after surgery.

CONCLUSION

It is suggested that posterior shift of IOL following use of CTR should be kept in mind and the IOL implanted should be of + 1.0 to 2.0 D more than that calculated preoperatively.
