1. Safety and efficacy of intracameral mydriatics in cataract surgery
Sammanfattning : Background: In order to perform cataract surgery, adequate dilatation of the pupil is essential. This is traditionally achieved by preoperative topical mydriatic eye-drops, commonly cyclopentolate and phenylephrine. This routine has several disadvantages. First, the slow penetration through the cornea delays the onset of mydriasis. LÄS MER
2. The role of T-type calcium channels in human pancreatic β cell maturity
Sammanfattning : This PhD work has optimized a series of in vivo, ex vivo and in vitro approaches to recapitulate, intervene and appraise in vivo maturation of naïve β cells within human induced pluripotent stem cell-derived islets (hiPSC-islets). These approaches have also been applied to characterize hyperglycemia-induced dedifferentiation of mature β cells within native human islets grafted into the anterior chamber of the eye (ACE) of immunodeficient mice.

3. Posterior capsule opacification and postoperative endophthalmitis following cataract surgery : predictive and protective factors
Sammanfattning : Modem cataract surgery with implantation of an intraocular lens (IOL) is an increasingly safe and successful procedure, though complications still occur. This thesis addresses the most common complication, posterior capsule opacification (PCO) and the rare but serious complication postoperative endophthalmitis (POE). LÄS MER
4. Aspects of aqueous humor dynamics : Studies in vivo and in vitro
Sammanfattning : The purpose of the present investigation was to study the effects of PGF2α-l-isopropylester, some neuropeptides, and pharmacological agents on aqueous humor dynamics and intraocular pressure (IOP) in vivo and on adenylate cyclase activity in the nonpigmented ciliary epithelium (NPE) in vitro.Pituitary adenylate cyclase-activating polypeptide (PACAP) and vasoactive intestinal polypeptide (VIP) caused a dose-dependent increase in cAMP formation, indicating that the NPE contains receptors for PACAP and VIP coupled to adenylate cyclase activation.

5. Safety and efficacy in the cataract surgery process
Sammanfattning : BackgroundCataract and age-related macular degeneration (AMD) are two major causes for visual impairment in the elderly. Cataract surgery is one of the most common surgical interventions performed in the western world. As a consequence of the increasing number of operations performed, postoperative visits are a large workload for surgical units. LÄS MER
